Application July 18, 1936, Serial No. 91,333`

2a chime V(ci. :5r-15) l My present invention relates primarily to the 'art ot beverage conditioning and dispensing and is more especially concerned with the cooling and dispensing of beer and kindred beverages including the `brews commonly known as ale, fporter, Weissbier, saki and the like.

Among the objects of the invention are to provide a brew keg or barrel which may be substantially conventional in external form or appearance whether made of wood or of metal, winch admits of being filled or charged by conventional brewers' racking apparatus, of being tapped by conventional draft apparatus and of :being cleaned or pitched by conventional apparatus for that purpose, which is devoid of any delicate parts apt to become injured in the usual rough handling of such units during shipment from or return to the breweries, and which is of particular utility in the operation of the cooling and dispensing method, and as a constituent element of the installation disclosed and claimed in my copending application, Serial ;No. 759,440, filed December 28th, 1934, and patentedfAugust 11th, l936,under No. 2,051,013.

Another object is to provide a barrel or keg unit of the above character the features oi' which may. be embodied in units of conventional overall dimensions without reduction in the brew containing capacity thereof, despite the presence of the cooling instrumentality built thereinto, and .without in anywise increasing the likelihood of impairing the brew within the barrel by undesirable escape of gas or brew therefrom or entry of air or foreign matter thereinto.

Another object is to provide a barrel or keg of the above type, which admits of being readily connected up by the bartender as a constituent element of the installation of my patent above identified for performing the method thereof, without the use of tools for the purpose and which may as readily be disconnected for replacement after .the barrel ,is empty.

Another object is to provide a unit of the above type from which properly cooled brew may be dispensed relatively promptly, even while the major content of the barrel if delivered relatively warm from the brewery, has not been effectively cooled.

Within the scope of certain oi the claims of the present application are numerous specific embodiments, some of which are disclosed in my prior copending application. Serial No. 688,779, tiled September 9, 1933, and others of which are disclosed in my copending application above identified, of both of which prior applications,

the present application is a continuation in part.

A feature of the invention is the incorporation of a heat conductive instrumentality within the barrel orkeg in direct contact with the containedbrew by which heat may be abstracted 5 when the unit is set up in the installation of the above identied patent, to bring the contents to and maintain it within. the predetermined dispensing temperature range desired, so ,that the brew may be dispensed directly from the barrel without traverse through auxiliary cooling appliances. Desirably this vinstrumentality is a conduit built into the barrel through which cool ing iluid preferably cold water, is circulated. said conduit exposing a relatively large heat abstracting area to the brew, eiective to bring down to desired 'dispensing temperature within a reasonable period ofl time practical in the aver'- age tavern, the contents of a barrel, even though it has been warmed to a temperature of 55 degrees F. or more at the time the barrel is connected in the installation.

Another feature is the disposition of the major portion of the cooling instrumentality below the level of the filling bunghole and preferably nearA 25 the bottom of the barrel to av'oidinterference with the filling or racking tube when inserted through the filling bunghole or of the usual draft tube when inserted through the draft outlet, and also to apply the most intense cooling effect near the bottom of the barrel from which region the brew is drawn.

In a practical embodiment specifically shown, the cooling conduit comprises a unitary metal tubular conduit or pipe of length greatly in excess of the depth of the barrel, the major length of the pipe extending in a. series or sequence of similar preferably identically spaced and generally parallel runs which illustratively are in the form of convolutions preferably helical convolutions, the ends of which are, preferably connected to the upper head of the barrel. In the embodiment shown, the major area oi' the'cooling instrumentality is in the lower half of the barrel below the lling bung and risers connect respectively to the inlet and outlet at the upper head. v

While the invention may be `incorporated in wooden or metal barrels specially built for the purpose, it lends itself readily to the adaptation 50 of conventional wooden beer barrels for the purpose. For that purpose, the conventional stave construction and lower head may be utilized, but the upper head' merely, to which the ends of the cooling structure are amxed, is modified so that 55 Y tional, except that the crozes are disposed eachl in eroze II.

its major thickness extends above the croze and a suillcient additional effective depth is ail'orded 7to compensate for the volume' of the cooling coil. In wooden barrels specially built for the purpose, the staves and heads may be quite convennearer the respective rims of the barrel.

In the accompanying drawing in which are shown one or more of various approved embodiments oi.' the several features of the invention.

Fig. 1 is a view in longitudinal cross section of a wooden barrel modiiled in accordance withl the invention,

Fig. 2 is a fragmentary sectional detail view on a larger scale showing one of the terminal connections from the cooling coil inthe barrel head prior to connection into the cooling circuit,

Fig. 3 is a view similar to Fig. 2 with a closure in place therein,I

Fig..4 is a view similar to Fig. 2 showing the terminal as connected, and

Fig. 5 is a view similar to Fig. l of an alternative embodiment oi the invention.

In Fig. l is shown the conventional wooden beer barrel, with the usual lower head I0 fitting 'Ihe upper head I2 may have the usual tap bushing I3 plugged by the usual cork il after the barrel is filled. I'he upper head, however, is modified to carry the heat abstracting element, preferably'a coil I5 of metal tubing. The cooling coil may include a number of convolutions I6 rising in helical form from slightly above the bottom oi' the barrel and olf outer diameter. somewhat smaller than that of the head, as shown. The unitary piece of tubing I5 includes at one end a riser Il rising from the lowermost convolution and at the other end, a shorter riser I8 rising from ktheupperrnost convolution, said risers connected at their upper ends in liquidtight relation. to Acorresponding connections I9 with respect to the barrel head.

The connections mounting the risers of the cooling coil are preferably in a diametral plane at right angles to the axis of the illling bung hole 2li and the cooling coil is wholly below said hole. Accordingly, there is no interference with the insertion of the conventional brewers lling or racking tube commonly extended across the entire diameter of the barrel in charging or nlling.

' Desirably the tubing I5 is of a metal of sufficient strength to withstand the mechanical shock to whlchtransporation brew barrels are commonly subjected in the course of handling, as for example of stainless steel. Among other materials suitable for the purpose are certain special alloys mainly of copper. Where the tubes are made of copper alloy or the like, the outer wall thereof is preferably coated with silver or with tin, which are neutral to the brew.`

In one desirable embodiment in extensive commercial use, the half barrelsV or kegs of conventional size of ll/ gallons capacity are equipped with coils of the silver plated copper alloy which coils are outer diameter and have a wall thickness of .042". The coil conformed as previously set forth and asv shown in the drawing is somewhat over` 14 feet long and exposes to contact with the brew a relatively large surface area, in this instance, 335 square inches. By the arrangement set forth, the cooling conduit\ex poses to the brew within'the barrel a relatively large area per unit of volumetric capacity of the barrel, in the neighborhood of 25 square inches Iper gallon. The cooling conduit submerged in the l brew remaining in the lower half o! the barrel v when the same has been half emptiedpresents a surface area exceeding 35 square inches per gallon. By virtue o! this construction whenV cold water at temperature but little above the freezing pointis pumped through thecoil it will abstract heat and the brew will be brought down to the desired dispensing temperature in a period o! time so short as to be entirelyv practical for use in theaverage tavern. In actual practice; especially in hot weather. the brew in the fresh barrel when delivered to the tap roomv may have been warmed to a temperature oi around 60 F. When the keg with its contents thus warmed is connected vup in the 'cooling line it will be seen that a sharp temperature gradient exists between the brew around the coil and the cold water flowing within the coil, so that heat is rapidly abstracted from' the brew through the thin conductive metal wall of the coil andis carried away by the circulating water so that in the continued circulation the temperature gradient between the brew and the water drops as the beer is cooled. Since the major cooling area is near the bottom of the keg, the region from4 which the brew is drawn, disy pensing temperature at that locality is reached in tially at that temperature by compensating for the rise in temperature of the brew that would otherwise occur by slow conduction of heat from the warm tap room through the wall of the keg.

The connection I9 by which the ends of the cooling tube are connected to the keg head I2 may be ofv any of a wide variety of constructions, one of which is illustratively shown in Fig. 2. The aperture I2' in the barrel head has a tapered bore at its lower face for accommodating a tapered bushing 50 which mounts the upper end of the riser which fits snugly within the length of said bushing and `is swaged outward near its upper end 5I into a corresponding groove 5I in the bushing. The bushing is securely wedged in place by screwing over the upper nipple end 52 thereof a tapped collar 53 inserted into the upper end of the hole l I2. By this arrangement a mechanically secure and liquid tight connection is afforded which however is releasable should occasion arise to replace the head or the coil.

The bushing Sill has a skirt 5B' of length adeouate sumciently to steady the risers oi the coil to prevent excessive or destructive vibration in handling or transit of the empty barrel. 'It is understood that the cooling coil is further steadied against vibration by the incompressible liquid contents in transport of the full barrel.

For many purposes the brew filled barrel may be handled and delivered with the threaded sleeve 53 open because any dust or particles that might enter into the cooling coil would promptly be washed out after the keg has vbeen set up on the cooling line. However the threaded sleeve 53 may readily be closed to exclude foreign particles prior todelivery of the filled barrel to the tap room. For this purpose the sleeve 53 is formed with a ledge 54 for accommodating a disk of cardboard, celluloid or -the like such as a milk bottle cap which is adequate for the purpose.

Any suitable releasable coupling'is used to connect the branch outlets from the cooling fluid header to the collars 53. In a desirable construction shown in Fig. 4 an elbow 55, bearing a' exible gasket 51 at its lower lip 58 is clamped against the end of bushing lil, by means of a bushing l screwed into collar 53. The flexible branch outlet (not shown) is drawn over the upper end of elbow 56. It desired a friction plug (not shown) may be used in place of bushing 59.

The invention is applicable to brew barrels of standard capacity at present in use, the effective capacity of which according to 'the invention is not altered despite the space occupied by the cooling coil. For this purpose the head l! is conformed unlike that of the conventional barrel head, the main thickness of which extends below the conventional croze 2 I, but as shown the maior 'thickness projects above the croze. Approximately BI cubic inches effective volume of the key occupied by the particular cooling coil above described would be compensated for by thus adding approximately to the effective height of the interior of' the barrel.

It is seen that the head as thus modified is still as thick and substantially as strong as the conventional head despite the fact that by this modication there is added sufficient effective capacity to compensate for the presence of the coil. For installing the cooling unit in a conventional barrel it is merely necessary to remove the upper two' hoops 22 and 23, to loosen the third hoop 2l without disturbing the fourth hoop 25 'which holds the staves together, then to apply the new head l2 with its attached cooling coil and to reapply and retighten the hoops.

While according to' the foregoing disclosure the barrels in use may be rebuilt to incorporate the cooling coils or new barrels may be thus built, it may be desirable for the latter application to use as the upper head the conventional construction used for the lower head but to attain the added volumetric capacity to compensate for the presence of the coil by disposing the crozes nearer the respective rims of the keg.

Wooden beer barrels have to some extent been superseded by metal barrels and in Fig. 5 is shown the application of the present invention to one construction of such metal barrel for cooling and maintaining the beer cooled therein. The barrel illustratively shown, comprises complementary inner half barrels and 3i, welded together at their contacting rims and complementary outer half barrels 32 and I3, similarly welded together, to determine therebetween a space which may serve to provide a heat insulating jacket of dead air or partial vacuum, but which is ordinarily filled with a suitable insulating stufng 34. The lower head of the barrel includes stiiening structure 35 interposed between and engaging the inner and outer head elements thereof. The 'upper head' is similarly provided with stiffening structure 36 between the head elementsI 31 and I8 there-of. The tapping or tap bushing 39 iixedly connects the middles of the upper head elements and is plugged by the usual cork 40 before the barrel is filled. Preferably the structure is strengthened by metal ribs 4i intervening between the inner and outer wall elements of the barrel.

The metal barrel construction, which as thus far described Ais known and not my invention, is modified to accommodate the cooling coil I5 of the same conformation shown in the wooden barrel tached by connections I9' preferably similar to those shown in Fig. 2.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:-
